    以断续导通模式下的电流型开关电感Buck-Boost变换器为研究对象,根据开关电感变换器的离散映射模型,首先由Matlab数值仿真分析了电路系统的非线性动力学行为。其次采用参数共振微扰法对电路系统的混沌进行了控制,通过理论分析和数值仿真得到了扰动强度、扰动相位的合适取值。最后进行了相应的Matlab/Simulink仿真和试验电路验证,试验结果与仿真结果一致,研究结果表明参数共振微扰法可有效地抑制电路系统的混沌。Based on the discrete mapping model of switched inductance converter, the nonlinear dynamic behavior of the circuit system is analyzed by Matlab numerical simulation. The nonlinear dynamic behavior of the circuit is analyzed by Matlab numerical simulation. Secondly, the chaos of the circuit system is controlled by the parameter resonance perturbation method. The appropriate value of the disturbance intensity and the disturbance phase is obtained by theoretical analysis and numerical simulation. Finally, the corresponding Matlab / Simulink simulation and test circuit verification are carried out. The experimental results are in agreement with the simulation results. The results show that the parametric resonant perturbation method can effectively suppress the chaos of the circuit system.
